AI Technical Summary

Benefits of technology

The design provides a reliable, leak-proof, and freeze-resistant water delivery system for roof-mounted equipment, ensuring efficient operation and preventing contamination, while simplifying installation and reducing the risk of freezing and cross-contamination.

Problems solved by technology

Unfortunately, each of the techniques depends on the lack of human error in their installation to assure satisfactory performance.
If the enclosure is poorly made, fitted or sealed, then there is a risk of leakage.
If the insulation is not properly installed, then there is the risk of a pipe freezing during colder weather.
As shown In FIG. 24, the watertight seal at the pitch pan is subject to problems simply because the post hydrant extends well above the roofline.
For example, while being used, it will be easy to pull and then push the post about with significant leverage, and thereby create potential sources of leakage.
Similarly, the hydrant in FIG. 24 may be subject to disruptions of the seal at the pitch pan.

Embodiment Construction

[0043]FIG. 1 is an isometric view of a pedestal hydrant that illustrates exposed components. As shown, stainless steel shroud 1 encases the angle globe valve 3 that includes both a threaded inlet and outlet. Hose fitting vacuum breaker 4 extends through the shroud from the valve through a hole or aperture in the shroud. Dome handle 5 is shown before attachment to the valve item. A stainless steel base 2 is secured to shroud 1 by a continuous welded seam 8 that extends around the perimeter of the shroud. At the lower extreme of the pedestal hydrant, there is shown a short threaded length of pipe 6 and a threaded tee 7. These components will be discussed hereinafter.

[0044]FIG. 2 is a sectional view of FIG. 1 showing a full view of valve 3. Threaded pipe length 6 is shown as an extended length of a galvanized plated steel pipe that extends from the inlet of valve 3 and downward beyond the full length of shroud 1. Pipe length 6 is secured in place at stirrup 14 by set screws 15, which b...

Abstract

A fluid delivering hydrant providing a valve actuated assembly with enclosing shroud and water resistive doom handle assembly to protect the assembly from exposure to the weather while preventing entry of rainwater into a building structure upon the roof of which the device has been installed. The fluid hydrant also includes structures for preventing water or fluid from remaining in the hydrant after the fluid flow valve is closed. This presents possibly freezing of the fluid and damage to the system.

Description

[0001]This application is a Continuation-In-Part of U.S. Non-Provisional patent application Ser. No. 10 / 146,211, filed on May 15, 2002 now U.S. Pat. No. 7,143,779, entitled “PEDESTAL HYDRANT,” which application claims the benefit of U.S. Provisional Patent Application No. 60 / 294,174, filed on May 29, 2001, entitled “PEDESTAL HYDRANT,” which applications are incorporated herein by reference.FIELD OF INVENTION[0002]This invention relates to fluid delivery devices exposed to extreme cold temperatures.BACKGROUND OF THE INVENTION[0003]In the field of construction and, especially instances relating to the plumbing trade, it is common to install a source of potable water on a flat roof. The source is often a water hydrant or bibb that permits maintenance personal to use the water to hose down or wash equipment mounted upon the roofs surface. Such equipment would include roof top air conditioners and exhaust fans that periodically require cleaning in order to assure efficient operation, voi...
